boss 18. In this manner the frog 12 is re` tained in place within the recess and yet may have transverse sliding movement so as to bring its channels 15 or 16 into selective alinement with the respective channels y 9 and 10. The body 7 at its end opposite its end which is provided with the boss 8, is formed with a recess 22 opening into the recess 11, and the side walls of this recess 22 occupy the 'same plane as the guiding side walls of the channels 9 and 10. At the opposite sides of the recess 22, the body 7 is recessed as at 23 to accommodate the connected ends of the other sections of the rails 2 and 3. f In order that the frog may be shifted across its base to position the frogy proper 14 for travelling of' the train over the main track or the siding, the body 13 is pro-vided at onel end with an ear 24 having an opening 25 in which is engaged the bent up end 26 of a rod 27. slidably mounted as at 28 upon one of the ties 5, this rod being adapted to be shifted under conditions and by means to be presently explained.

.The .switchv point, in this form of the invention, is indicated in general by the numeral 29, and the same may, if desired, ybe

formed from a length of ordinary rail or it may be initially formed of the required shape from other stock material. 1n any event'the point will comprise a head 30 corresponding in general Jform to a section of an ordinary rail head, a web 31and a base flange 32.v As distinguished from the ordi nary switch point which is swiveled at its butt-end to the main or siding rail, as the case may be, and is adapted to be swung toward and away from the companion rail, the point embodying the invention is hinged at the edge of its base flange as at 33, to the ties or any other base structure which it may be found advisable to employ, and the'point is adapted to be moved upon its hinges so as to occupy a position resting against the side of the rail or a position tilted away from the rail to permit of passage ofthe wheel flanges. 1n order that a smooth and unobstructed surface may be provided at the treads or heads `of the rails where the switch point meetsthe companion rail, the said companionrail preferably has one side of its head formed with a shallow recess 34 into which the tongue of the point is adapted to seat when the point is swung up to position beside the rail. This recess is as stated, shali low, so` that even when the point is away from the rail the wheel flanges may pass the recess without any battering of the rail or injury to the wheels. At the same time when the tongue of the point is seated in the recess, the outer or guiding side of the head or the point will be flush and even with the corresponding side of the head of the rail and there will be no likelihood of damage to the point when the wheels pass over' the same. In the form of the invention shown most clearly in Figs. 1, `4, 5 and 6 of the drawings, the operating means for the switch points comprises a bar 35 whichl is pivoted at one end as at 36 to the under side of a plate 37 secured upon the ties 5, the bar extending between two adjacent onesof the ties and beneath the rails and the witch points associated therewith. The base Hangs of each rail is cut away at a suitable point as indicated bythe numeral 38, this cut portion beingin the side of the `flange next adjacent the switch point, and the bar 35 is formed with an overhanging lip 39 which is adapted to ride over the'upper side of the base ilange of the rail in the movement ott the bar 35 about its pivot. The bar 35 is also provided with a similar lip 40 which engages over the base flange' 32 ot' the switch point 29. Alsothe bar is formed between the lips 39 and 40 with an upstanding tongue41, the upper end of which may be slightly deflected laterally toward the lip 40 as indicated by the numeral 42 to ride against the inner side of the web 31 of the switch tongue pointv 29. Of course, the bar 35 will be provided with two sets of the elements 39, 40 and 41 for coaction` with the two switch points which extend above the bar. The tongue 41 is accommodated within the cutout portion 38 of the base flange of the rail with which the respective switch point coacts, and it will be understood that when the bar is swung about its pivot in either direction, one of the lips 40 thereon will ride against therespective switch point and swing the same about its hinges to upright position against the companion rail as shown clearly at the left of Fig. 4 of the drawings, the tongue `41 associated with the other switch point riding against the same to tilt the point about its hinges to position spaced from the companion rail as shown at the right in said Fig. 4. A swinging of the bar 35 about its pivot in the opposite direction will effect a reverse operation of the two switch points as clearly shown in Fig.5. 1n order that the bar 35 may be actuated a switch stand 43 is provided and comprises a suitable mounting 45 having a `finger 46 extending below its pivot yand 'working through an eye 47 swiveled to the end of the bar 35. 1n order that when the lever 45 is thrown to adjust the switch points., the frog 12 will be correspondingly automatically adjusted, a rod 48 is connected at one end to the bar 35 and at its other end to one arm ora isc' an angle lever 49 mounted, as at 50, upon one of the ties. The other arm of this lever has a pin and slot connection 51 with the sliding rodv27 and it will be evident by reference to Fig. l of the drawings and the full and dotted line positions shown therein, that movement of the bar 35 to throw the switch points for travel of the train upon the main track, will result in a corresponding adjustment of the frog 12, the frog being likewise adjusted when the bar 35 is moved to throw the switch points for travel of they train upon the siding. v

Fig. 8 of the drawings illustrates a modified form of frog and in this figure the b-ase or foundation of the frog is indicated by the numeral 53 and the frog is indicated by the numeral 54. The body 53 is similar in its construction to the body 7 of the frog shown in Fig. 3 of the drawings, and the frog 54 which is mounted upon the body or foundations 53, is similar to the frog 12. In

this modified structure, however, the body 53 is formed at opposite sides of the recess 55 which corresponds to the recess 11, with sockets 56 in which are fitted the right angularlyl turned ends 57 of a key plate 58 which plate extends across the respective end of the recess 55 and through a slot 59 formed in the respective end of the frog 54, it being understood that a pair of the key plates are provided and that they are arrangedvat opposite sides of the body 53. Pins 60 or other Suitable fastening elements may be ttedl downwardly through `openings 61 in the body 53 and through registering openings 62 formed in the ends 57 of the key plates so as to retain the plates in place.

In the form of the invention shown in Figs. 9 and 10 of the drawings the b-ase or foundation for the frog is indicated by the numeral G3 and is formed in its upper side with a recess 64 in which is disposed the frog proper indicated in general by the numeral 65. The said frog 65 comprises a substantially wedge-shaped body 66 which is freely shiftably mounted in the recess 64 transversely thereof, and a key plate 67 is fitted transversely through a slot 68'formed in the body 66 and secured by rivets or any other suitable fastening elements 69. The ends of this plate project slidab-ly through slots 70 formed in the opposite side walls of the recess 64, and one end of the key plate is provided with an opening 71 to accommodate an actuating rod corresponding to the rod 27.

In that form of the invention shown in Fig. 11 of the drawings, the switch points which are indicated by the numeral 2 are hinged at their base flanges as indicated by the numeral 73, and a. bar 74 is slidably mounted beneath the rails and switch points,

in suitable guides 75, and is provided with upstanding arms 76 pivotally connected as at 77, to the said switch points. An operating lever 78 is pivotally mounted as at 79 and provided with an arm 8O which works through one end of the bar 74,' and it will beevident by reference to the said ligure'- that when the lever is rocked in one direction, one switch point will be thrown to position beside its respective rail and the other point away from its respective rail, and when the lever is swungk in the opposite direction the position ofthe switch point will be reversed.

'In the form of the invention' shown in Fig. 12 of the drawings the frog is similar in construction to that illustrated in Fig.`

9, except that inthis case it may bemade by a combination of suitable pieces of ordinary rail and is disposed upon a metallic base plate 81, the structure being secured in place by any suitable means 82.

, It will kbe understood that while several forms of the frog and its associated parts and several forms of the switch point and its associated parts have been illustrated and described, such illustration and description is to be taken merely as representing possible embodiments of the invention, the principles of the invention being capable of embodiment in various other structures if found desirable.

Having thus described the invention, what is claimed as new is:

1. In a railroad switch, the combination with main and siding rails,`of a supporting base arranged at thel cross over of two of sald ra1ls and having a transverse recess 1n its upper side and having guiding faces alinin with the' respective rails, a frog shifta le inthe recess and having channels for alinement with the respective rails, a

versely thereof intowhich kthe channels` open, and a. slot in the bottom of the recess,

a frog shiftably mounted in the recess 4and havin channels for registration selectively with t e first-mentioned channels,a boss depending from the frog into the slot in the base, a keyfplate engaging the base and said boss to retain the frog 1n the recess in ther4 base, and means for shifting the frogv '105 key engaging thefrog and the base to re.

In testimonywhereof I aflix my signature.
